Hanner fampir, hanner tylwythen deg, cwbl unigryw! Mae Annalisa Swyn yn arbennig oherwydd ei bod yn wahanol. Tylwythen deg yw ei mam, a fampir yw ei thad, ac mae Annalisan gyfuniad or ddau. Mae hi wrth ei bodd âr nos, ystlumod a phethau du, ond mae hefyd yn mwynhau bod yn yr awryr agored a ddefnyddioi hudlath, ac maen caru popeth syn binc. Half vampire, half fairy, totally unique! Isadora Moon is special because she is different. Her mum is a fairy and her dad is a vampire and Isadora is a bit of both. She loves the night, bats, and the colour black, but she also loves the outdoors, using her magic wand, and the colour pink. When its time for Isadora to start school shes not sure where she belongs.
